9. Trading Trevor Ariza for Steve Francis

Even when Isiah did something right, he found a way to screw it up. The Knicks drafted Trevor Ariza with their second-round pick in 2004, and he showed early signs of being a steal. But then Isiah and Larry Brown took a flyer on washed-up guard Steve Francis, shipping Ariza to Orlando for Francis. Ariza eventually blossomed into a key contributor for a Lakers title squad.
